Ukugcinwa kwamanzi kusukaI-Hydroxypropyl Methyl Celluloseingenye yezakhiwo ezibalulekile zeHydroxypropyl Methyl Cellulose. Izinto ezifana nezinga lokushisa lomoya, izinga lokushisa kanye nesivinini somfutho womoya zizothinta izinga lokuguquguquka kwamanzi odaka lukasimende kanye nemikhiqizo esekelwe ku-gypsum. Ngakho-ke, ezinkathini ezihlukene zonyaka, kunomehluko othile kumphumela wokugcina amanzi wemikhiqizo enenani elifanayo le-Hydroxypropyl Methyl Cellulose engeziwe.
Ngokuvamile, ukuphakama kwe-viscosity ye-Hydroxypropyl Methyl Cellulose, umphumela wokugcinwa kwamanzi uzoba ngcono, kodwa umphumela we-viscosity ekugcinweni kwamanzi uzoncishiswa lapho i-viscosity idlula i-100,000 mpa.s. Ku-Hydroxypropyl Methyl Cellulose ene-viscosity engaphezu kuka-100,000, kuyadingeka ukwandisa inani le-Hydroxypropyl Methyl Cellulose ukuze kwenyuswe kakhulu izinga lokugcinwa kwamanzi.
Ekwakhiweni okukhethekile, umphumela wokugcina amanzi we-slurry ungalungiswa ngokwandisa noma ukwehlisa inani le-Hydroxypropyl Methyl Cellulose. Imikhiqizo yochungechunge lwe-Hydroxypropyl Methyl Cellulose ingaxazulula ngokuphumelelayo inkinga yokugcinwa kwamanzi ngaphansi kwezinga lokushisa eliphezulu. Ezikhathini zokushisa okuphezulu, ikakhulukazi ezindaweni ezishisayo nezomile kanye nokwakhiwa kongqimba oluncane ohlangothini olushisayo, i-hydroxypropyl methylcellulose yekhwalithi ephezulu iyadingeka ukuze kuthuthukiswe ukugcinwa kwamanzi odaka.
Ikhwalithi ephezulu yeHydroxypropyl Methyl Cellulose inokufana okuhle kakhulu. Amaqembu ayo e-Methoxy ne-Hydroxypropoxy asatshalaliswa ngokulinganayo eceleni kweketango lamangqamuzana e-cellulose. Ingathuthukisa ama-athomu omoya-mpilo ku-hydroxyl ne-ether bond. Ikhono lokuhlangana kwamanzi ukwenza amabhondi e-hydrogen liguqula amanzi amahhala abe amanzi abophekile, ngaleyo ndlela alawule ngempumelelo ukuhwamuka kwamanzi okubangelwa izinga lokushisa eliphezulu kanye nokuzuza ukugcinwa kwamanzi aphezulu.
Ikhwalithi ephezului-hydroxypropyl i-methyl celluloseingahlakaza ngokulinganayo nangempumelelo odakeni lukasimende kanye nemikhiqizo esekelwe ku-gypsum, igoqe zonke izinhlayiya eziqinile, futhi yakha ifilimu emanzi, futhi umswakama osekelweni uzokhishwa kancane kancane isikhathi eside. Ukusabela kwe-hydration kwenzeka nge-inorganic gelling material, ngaleyo ndlela kuqinisekisa amandla ebhondi namandla acindezelayo wento. Ngakho-ke, ekwakhiweni kwehlobo lokushisa eliphezulu, ukuze kuzuzwe umphumela wokugcina amanzi, kuyadingeka ukwengeza imikhiqizo ephezulu ye-Hydroxypropyl Methyl Cellulose ngobuningi obanele ngokusho kwefomula, ngaphandle kwalokho, i-hydration enganele, amandla ancishisiwe, kanye nokuqhekeka kuzokwenzeka ngenxa yokomisa ngokweqile. Izinkinga zekhwalithi ezinjengomgodi, ukugoba nokuwa nazo zandisa ubunzima bokwakha kubasebenzi. Njengoba izinga lokushisa lehla, inani le-Hydroxypropyl Methyl Cellulose elingeziwe lingancishiswa kancane kancane, futhi umphumela ofanayo wokugcina amanzi ungafinyelelwa.
